    2008 Tahoe Hybrid Engine Temp Rises in Auto/Stop

    Updating this with details from a little over a year later. Water pump failed on me today. Not related to this, I don’t think, but I found that the little impeller on the auxiliary coolant pump that runs to one of the heater hoses was plugged up. Specifically with the remains of the previous...

    Transmission removal for rear main seal replacement

    I’m actually considering just taking out the engine at this point. I might as well do the front and rear covers at the same time. I’ll keep the thread updated. Going to talk to a mechanic on my street to see if I can hire him to tackle it with me

    Transmission removal for rear main seal replacement

    Howdy! Anyone know if the rear main housing/gasket assembly can be replaced without disconnecting the transmission high voltage cables to the hybrid module? Referring to pulling the 2ML70 apart from the 6.0. It’s visibly leaking from the passenger side rear housing gasket above the oil pan...

    6.0L valley cover gasket

    Appreciate the suggestions. Yes it was leaking from several areas around the VLOM because of it being loose and the gasket was shot. It was also been leaking from the 5 pin connector on the original VLOM. I’ll do some research on the AFM issues you mentioned. Currently at 168k miles. I usually...

    6.0L valley cover gasket

    Update! Yea AFM is active and working. My attempt at using RTV and torquing down the original VLOM was not successful. It kept on leaking after a few minutes and was shiny all around it when I took the intake off again. I ended up finding the updated VLOM at the dealership and popped it in. It...

    6.0L valley cover gasket

    Holy crap! https://www.tahoeyukonforum.com/threads/vlom-valley-cover.119859/ Most of the bolts on my cover were lose! I was able to take them out by hand. WTF. On a second note, this post also said the cover I have on my 08 Tahoe is not the revised cover, which you have, j91z28d1 I’m...

    6.0L valley cover gasket

    Thanks! I’m researching. It doesn’t look like I can take it out without breaking the little plastic connectors to the inner gaskets. Hmmm

    6.0L valley cover gasket

    Hey all! I found a bad leak coming from the valley cover gasket. However, it’s a whole assembly, Damnit! anyone else replace one of these or know if you can get just the gasket?

    [Help needed] Silverado Hybrid stock HP Tuners file

    Hey Brotha! Would you happen to know what year those updates for the Trans and 2 motor controllers came out? I have an 08 hybrid and I THINK the dealer did those updates at one point but just curious if you have any more details? Perhaps a bulletin on what those updates are supposed fix...

    2008 Tahoe Hybrid Engine Temp Rises in Auto/Stop

    Hey all! I completely spaced to reply here what I ended up finding the cause of the problem to be. My thermostats rubber portions had fallen apart and were very brittle. It was allowing water through and causing the system to not work properly, as soon as I took the housing off, there it was...

    2008 Tahoe Hybrid Engine Temp Rises in Auto/Stop

    Thanks so much for the input! The more that I researched I was able to put together that the pump under the coolant tank and the one farther down the line towards the driver side are only for the hybrid component cooling. I'm sure if those failed you would get a warning or message. The pump...

    2008 Tahoe Hybrid Engine Temp Rises in Auto/Stop

    Hello! The engine temperature needle goes past 210 when the Tahoe enters into Auto/Stop. The temp levels out and stays right at 210 when the engine runs. Coolant reservoirs are where they should be at. My first thought is that the little auxiliary pump motors that are in-line with the...

    2008 Tahoe Hybrid 12v Battery Constantly Dying

    Howdy, Happy to report that the + cable stopgap did prove one of the problems was at the original battery terminal/cables . The cables that were shorting out in the loom and repaired have made the issue with electrical issues go away completely. The new + cable assembly arrived and I installed...
